Background technique

In recent years, with the rapid development of my country's economy and the rapid development of the central heating business, the heating scale has become larger and larger, and the hydraulic imbalance in the heating system has become more and more obvious. In a building, the water volume of each heating equipment does not match the design water volume, the flow of near-end heat users is large, while the flow of far-end heat users is small. Usually, the method of increasing the flow rate of the heat exchanger and the circulating water pump is used to alleviate the contradiction. As a result, the project investment increases and the operating cost increases. The imbalance of the hydraulic working condition is eliminated by increasing the power consumption and heat loss, resulting in the same heat supply in the heat source. In some cases, the temperature of the water supply cannot be increased, the temperature of the return water cannot be lowered, and the heat cannot be fully utilized. In a large-scale heating pipe network system, only by installing control elements with automatic adjustment function to realize the dynamic balance of the pipe network, can the phenomenon of hydraulic condition imbalance be completely solved and the heat supply quality of the whole system can be ensured.

The existing flow regulating valves either cannot manually set the working flow according to the actual situation of the user's needs, or the automatic balancing valve group has weak balancing ability and unstable balancing device, so it is not suitable for large-scale heating pipe network systems with high flows, The harsh environment of high pressure and high temperature is easy to damage and increases the difficulty of maintenance. Therefore, it is particularly important in the heating system to provide a balance valve that is stable and not easily damaged, and can manually adjust the working flow.
